Using Word 2000. I have what appears to be a fairly standard size envelope
for greeting cards. The envelope measures 7 inches wide by 6 inches tall.
Many of the "standard" envelope selections in Word are given in "mm" and my
conversion skills are pretty rusty.

Does this 7 inch by 6 inch greeting card envelope fall under any of those
standard selections, or do I need to create a custom size envelope every
time I want to print a greeting card envelope?
